If you are a serious runner and will be using the jogger mostly for running, you will want to get a jogger w/a fixed wheel and a long wheel base. The reason is that it will not track straight. It will pull to the side and drive you crazy.

There are better joggers than Bob if you want it for jogging. We have a Bob, which I love for walks, but DH hates it for jogging. They even say it's not meant for jogging, even though it's a jogger. If you want something that is all purpose, and will mostly use it for walking or at the mall, etc. then a Bob is great way to go.

i'm so glad someone posted about this- i'm at a loss with all these jogging strolllers- and my husband insists- what about when you have one child over 50lbs and a newborn? are you just suppose to get a single and leave one at home? my daughter is only 4- but she's too heavy for any stroller made for 2 children
